How is intensity related to loudness?
Assuming we are talking about sound, intensity measures the power in a sound wave. Mathematically, it is the product of the sound pressure and the particle velocity, and is measured in watts per square meter. Loudness usually refers to the (subjective) perception of sound intensity by people. It is related to intensity, but also depends upon frequency. The human ear perceives increases in sound intensity roughly on a logarithmic scale, so for example the sound intensity needs to increase by about a factor of ten to create the perception that the sound is twice as loud. This is the motivation for the decibel system, which measures sound intensity on a logarithmic scale.
What instrument measures noise level?
Sound level meters Loudness meters Noise dosimeter
Sound intensity decreases when what decreases?
Sound intensity decreases when amplification (volume) decreases.
What describes the intensity of sound?
Sound intensity or acoustic intensity is defined as the sound per unit area. The usual context is the noise measurement of sound intensity in the air at a listener's location as a sound energy quantity.
What is intensity in sound?
Sound intensity (I) is a sound energy quantity in oposite to sound pressure (p), which is a sound field quantity. I = p². Sound intensity or acoustic intensity I is defined as the sound power Pac per unit area A. That is: I = Pac / A. The usual context is the noise measurement of sound intensity in the air at a listener's location.
What instrument measures luminous intensity or flux?
Luxmeter measures luminous intensity. The SI unit of luminous intensity is candela (cd).
What instrument measures uterine depth?
A uterine sound measures uterine depth.
Is a photometer an instrument that measures the intensity of the incoming light and quantifies it into numerical data?
Yes. A photometer is an instrument that measures the intensity of the incoming light and quantifies it into numerical data. A photometer is a light sensitive device and measure the power of light.
What instrument measures density of an earthquake?
A seismograph records the intensity measured by the Ritcher Scale.
What instrument measures the volume of sound?
a decibel meter.

What instrument measures the amplitude of sound on a mobile?
A frequency meter is the instrument that is used to measure the amplitude of sound. It reads the energy from a sound wave.
The unit of measuring the intensity of sound is kept after the name of which eminent scientist?
instrument for measuring sound was named after which scientist?
Is seismograph a type of technology?
A seismograph is an instrument that measures the intensity of earthquakes. Seismograph technology would refer to the science involved with the design or improvement of the instrument.
How is the loudness of a sound related to the amplitude?
Loudness is really a subjective measure and is often confused with objective measures in decibel units of sound pressure or sound intensity.
What instrument measures decibels?
Most famous is a SPL meter (Sound Pressure Level).
What machine measures sound intensity?
The instruments are variously known as sound level meters, noise meters, noise dosimeters, acoustic transducers, etc.
